Its been a while since I was heavy into Bomes, but it’s basically a customizable midi translation.
Anything you send IN, can be translated to ANYthing else OUT.
For example, I could build a preset for my keyboard on say midi channel 15, I could make note C-3 on press, set effects values on the AR A4 and OT, play various sample tracks, apply pressure to a AR perf pad, and adjust perf values on the A4, on release, go back to where it left off.
Thats an elaborate example, but it would be possible.
I would probably end up doing stuff like making various notes/channels from a keyboard, do different things.
Ch 11 might, play a flange or a comb filter, or both with reverb on a few keys.
Ch 13 might be like a keyboard split, one octave playing A4 sound, another octave playing OT samples, another octave playing a bassline on the A4, use the velocity to change other parameters.
Set up conditional midi trigs on the OT, to perform vast functions.
